      Ron, I guess you're the Cobalt 2 Guru and for that, I thank you. Got a bit of a problem. My battery ran completely dead. Now it will not charge or turn on (not sure which). I did the manual reset and the bootloader window came up as expected. I copied the latest firmware file into the bootloader directory and ejected the device. Nothing. Can you suggest anything? Thanks in advance!

        I'm going to start a ScubaBoard "conversation" with you as this area is very limited as to message size. 1st thought: are you doing the reset with the USB still connected? that will put it into boot mode. it needs to be unplugged.

      Dear Ron,

      I hope this post finds you well.

      I understand you are the go to person for Cobalt troubleshooting.

      In short, the compass has disappeared on my cobalt 2 screen. When I press the button it will let me set bearings such as 90, 180 etc, however no compass appears. I have updated the firmware and restarted the unit. I am now at a loss as to what more I can do. Any insight would be much appreciated.

        Sorry for the delay in replying, I missed this as a message.
        If your compass doesn't display, it is because the firmware is not getting good data from the compass chip. There are limited to messages in this part of ScubaBoard, so I am sending you a message to help with diagnostics. -Ron

      Dear Ron, no doubt you did answered that many times. Can I get some instructions how to fully reset divelog in Cobalt2. I need to pass the device to another person. Thank you!

      Can I get instructions on restarting a dead Cobalt 1, the 2 others we have started fine from a dead battery. One isn’t cooperating! Thanks

      Hi Ron! Browsing this forum I have realized that you might be able to help with our non-booting and battery dead atomic cobalt 1. Based on the other threads it appears I need to pull the battery. Any chance you could advise?

      Hey Ron,
      I have a Cobalt 2 that wont power up. Its been in storage for about 2 months, so I figured the battery was just dead. After an overnight charge, nothing. Its warm from charging but still wont turn on. Ive tried both a 11 and 30 hold for a hard reset, and that didn't work either. When I took it from storage, it turned on for like 3 seconds with the reset time/date screen, but that was all I got out of it.
      1. RobCara
        Any help would be great! Thanks!

      Hello Ron,
      could you please again tell me how to clear the divelog? I purchased a used Cobalt2 and I am absolutely happy with it! Now I would like to get rid of my predecessor's divelog... just one minor issue- the upright button does not always work under any conditions... Acording to the serial#, my Cobalt2 seems to be built 2015. any suggestions how to improve it?

      Thank you so much for your help!

      After two years of flawless operation, on today's dive my Cobalt 2 stopped showing Dive Time (0) and NDL (--). It also stopped recording my dives in the Dive Log. I'm not sure what to do as i purchased it on line. Any advice would be greatly appreciated.
      Thank you very much,
      1. RonR
        First thing is to try to diagnose what the issue is. Most critically, does it display depth correctly? If so, the wet contacts might not be registering water, which can be due to grease or grunge on the pins at the Cobalt's nose.
